Description
Technical field
The present invention relates to edible oil manufacture field, more particularly to a kind of processing technology of oil tea.
Background technology
Oil tea is the big wood of the distinctive main woody edible oil material seeds of south China and the world four originating from China
One of this edible oil materials seeds, China's camellia oleifera lam area account for more than the 80% of woody edible oil charge level product.It is obtained from tea seed
The oil obtained is tea oil, and the aliphatic acid composition of tea oil is similar to table oil fat-olive oil, and unsaturated fatty acid content is more than
80%, there is very high nutritive value；Traditional mechanical high-temperature squeezing is easily destroyed vitamin isoreactivity substance, simultaneously
Due to the particularity of tea oil, conventional refinery process cannot effectively remove soluble impurity.
The content of the invention
It is an object of the invention to provide a kind of processing technologys of oil tea, can improve refining oil yield, reduction is produced into
Originally product quality and stability, are improved.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of processing technology of oil tea, comprises the following steps：
1) tea seed, removal wherein impurity are chosen, obtains pure tea seed；
2) shell：By the shelling camellia seeds of gained, the camellia seed kernel of certain shell-containing rate is obtained；
3) dry, is broken：Camellia seed kernel is inserted 60 DEG C of baking ovens to dry, tea seed is dried to moisture less than 8%
It takes out afterwards and carries out break process, tea seed is crushed using double-roll crusher, control degree of fragmentation to tea seed 1/4-1/8
Valve；
4) cook：Broken tea seed is made into cake, by vapor boiling 1-2 it is small when, convenient for fuel-displaced；
5) cold pressing：Using double helix low-temperature oil expeller, loading frequency is arranged to 8 to 10 hertz for low temperature cold squeezing, squeezes
Bore temperature is arranged on less than 70 DEG C, and squeezing crude oil goes out bore temperature below 50 DEG C；
6) filter：Crude oil after squeezing is filtered impurity elimination so that the oil-tea camellia seed crude oil quality after removal of impurities is：Acid value
3.5, content of phospholipid 1.05%, moisture 0.2%, impurity 0.18%；
7) first time degumming：50% citric acid for accounting for oil-tea camellia seed crude oil total weight 0.01% is added in, then the 90 of addition 8%
DEG C hot water, together into being sufficiently mixed in static mixer, enter back into washing centrifuge and be dehydrated, first time degumming；
8) second of degumming：After first time degumming, 90 DEG C of heat for accounting for oil-tea camellia seed crude oil total weight 5% is added
Water, together into being sufficiently mixed in static mixer, enter back into washing centrifuge and be dehydrated, realize second of degumming；
9) middle temperature is dried：Crude oil after degumming is heated to 140 DEG C to 180 DEG C progress middle temperature is drieds；
10) decolourize：Activated carbon is invested in Decolouring pot than 1000: 1 according to crude oil and activated carbon weight, is warmed to 95 DEG C
To 105 DEG C, insulated and stirred 20 minutes；
11) it is deodorized：Crude oil after decoloration is placed in oil refining kettle, is warming up to 150 DEG C, is deodorized 40 minutes；
12) filter again：Crude oil is filtered using closed vibration filters, then is polished rear output product oil.
Beneficial effects of the present invention：The present invention is using cold pressing, the control that ensure that crude oil acid value to a certain extent
System and nutritional ingredient are not lost in, while improve the quality of crude oil and tea cake carries out byproduct deep processing and utilization value；Due to
Secondary washing and addition citric acid technique are employed, can largely wash away soluble impurity contained therein, improves production
Quality and stability.
Specific embodiment
Be described further below technical scheme, but claimed scope be not limited to it is described.
Embodiment 1
